PlNTLE-RETAINER FOR HINGES.

SPECIFICATION forming part of Letters Patent No. 765,152, dated July 12,1904.

Application filed June 6, 1903. Serial No. 160,350- (No model.)

To all whom it may concern:

, Be it known that I, GEORGE A. STARK, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPintle-Retainers for Hinges, of which the following is a specification.

My invention relates to pintle-retainers for hinges, and has for itsobject the provision of an improved device of this character which willbe simple in construction and reliable in operation.

A further object of the invention is the pro- I 5 vision of achamberedhinge-tip provided with a pintle-retaining device seated in anannular groove thereof.

A further object of the invention is the provision of means for securingthe pintle by what may be termed an end lock, as will be hereinafterdescribed.

In the accompanying drawings, Figure 1 is a view in plan and section ofa butt-hinge with my invention applied thereto. Fig. 2 is a longitudinalvertical section of one of the ornamental tips of a hinge, showing myinvention; and Fig. 3 is a transverse section on line 3 3 of Fig 2.

Like numerals designate similar parts 3 throughout the several views.

Referring to the-drawings, the numerals 5 5 designate the leaves of abutt-hinge having knuckles 7 7 for the reception of a pintle 8, thelatter having a knob or ornamental tip 8, as shown in Fig. 1. At the endopposite said knob the pintle is reduced to form a conical or taperingportion 8 terminating in a shoulder 9, and below said shoulder isoutwardly flared or inclined, as at 10, for a purpose here- 4 inafterstated. (See Fig. 2.)

Designated by 12 is an ornamental knob or tip provided with a flange l3and with an externally-threaded cylindrical shank 14:, said shank havingan inner chamber 15 and a circular groove 16, shown adjacent to the endof said chamber, although it may be differently disposed, one of the endknuckles 6 of the hinge being internally threaded, as at 17, for

the reception of said shank. Disposed in the groove 16 is a split ringor band 18, which when contracted may be readily inserted in said grooveand will be prevented from escape by the shoulders of the tip on eachside of the groove.

When the leaves of the hinge are assembled with the knuckles inalinernent, the chamber in the knob 12 will also be in alinement withthe pintle-opening, and when the pintle is inserted its end opposite theknob 8 will enter said chamber and pass through and expand the splitring 18, the latter immediately contracting around the reduced portionof said pintle and serving to retain it in position. Should it bedesired to remove the pintle, the knob 8 is grasped and pulled, and theflaring or wedge-like tip 10 will then expand the retaining-ring 18within the groove 16, which is of sufficient diameter to enable thisresult to be accomplished, until the pintle is released, when said ringwill immediately contract and resume its normal position.

In constructions with which I am familiar the pintle has been retractedby fastenings located in the knuckles of the hinge and clips on thepintle. These old constructions are more expensive to make and do notact as readily as could be desired. By locating the pintle-retainer inthe detachable knob of the hinge a simple construction results and onethat will operate efiectually at the point where most necessary.

Changes may be made in the form and proportions of the parts withoutdeparture from the invention, which is not restricted to the precisedetails shown and described.

Having thus described my invention, what I claim is 1. A knob for hingeshaving a chamber in the part thereof which enters the knuckle, combinedwith a pintle-retainer mounted in said chamber.

2. A knob for hinges having an externallythreaded and chambered shankfor closingthe end of the knuckle, said shank having a seat for apintle-retainer.

3. The combination, with a knob having a the knob; and a headed pint'lehaving an outwardly-flared and reduced tip and a shoulder adjacent tosaid tip, substantially as and for the purpose specified.

In testimony whereof I aflix my signature in presence of two Witnesses.

GEO. A. STARK.
